Abstract: COLOUR CATHODE-RAY TUBE APPARATUS                        ABSTRACT     Information about the position of an electron beam in a shadow mask colour cathode-ray tube is obtained by detecting a signal representative of the electron beam current inter-cepted by the shadow mask.  The signal may be derived by detecting the current generated by the electron beam in the shadow mask, or in the conductive layer at the tube screen, or by detecting the difference between the electron beam currents in the mask and at the screen.  In the latter case, the shadow mask and the conductive layer are connected respectively to the ends of the primary winding of a trans-former.  The difference currents are detected by a secondary winding.  A centre tap of the primary winding is connected to the tube EHT.  EHT isolation may also be achieved by optical or capacitive decoupling.  The shadow mask may have shaped apertures to generate distinctive difference currents.  In a preferred embodiment the apertures are slits or rows of slots extending from one side to the other of the shadow mask and a line raster is such that each line coincides with a different slit.  EHT isolation may also be achieved by optical or capacitive decoupling.

Abstract: ABSTRACT OF THE DISCLOSURE        In an analog to digital converter circuit for a CODEC a single reference voltage is used for comparing both positive and negative input signals.  The circuit comprises a capacitor array to define the decision levels corresponding to the end points of companding elements with the top plates of all capacitors in the array being connected in parallel through a single switch from an incoming analog signal source and to one input of a comparator.          The bottom plate of each capacitor is connected to one of a series of three-way switches, all of which have separate terminals con-nected to the output of a voltage reference, to separate switches on a linear resistor string connected to the voltage reference output, and to ground.  All switches are controlled by control logic connected to the comparator output.  Analog to digital con-version is achieved by zeroing the voltage on the top plate of a selected capacitor in the array when the voltage on its lower plate is manipulated by signals from the control logic operating the switches in the linear resistor string selectively.  By properly sequencing the switching of capacitors in the array, a single reference voltage is used.

Abstract: ABSTRACT             HEAT-ENGINEERING APPARATUS FOR CARRYING OUT THERMO-DYNAMICAL PROCESS COMPRISING A PAIR OF MUTUALLY OPPOSITE PHASE             TRANSITIONS OF A WORK MEDIUM         Thermo-dynamical processes which comprise mutually opposite phase transitions of a work medium are carried out in a heat-engineering apparatus composed of casings. The casings consist of spacers sandwiched by a pair of confin-ing plates. A casing encompasses one or a plurality of phase transition compartments which unit pairwise to work chambers in which mutually opposite phase transitions occur. If the phase transition compartments are located in different casings such casings are abutted against one another flat-wise along common confining plates. If complete work cham-bers are disposed in single casings, there are partitions which subdivide a casing in a plurality of phase transition compartments. In both oases the associated phase transition compartments open directly into one another through an orifice in the confining plate and the partition, respective-ly. Combinations of various confining plates and spacers permit to build heat-engineering apparatus such as multi--flash and multi-effect evaporators, sorption-type refri-gerators and the like by employing and associating casings of different types which comprise all auxiliary equipments such as condensing vessels, demisters, pressure reducing means, heat exchangers and the like. Required outputs will be obtained by selecting the number of casings accordingly.

Abstract: Method for the reconstitution, by filtering, of an analog signal, from a pseudo-analog signal obtained by a double, analog to digital, digital to analog conversions of the analog signal, with processing of the digital signal. In greater detail, the pseudo-analog signal, obtained by double analog to digital, digital to analog conversion of an analog signal, is applied to an active filter the impedance of which is controlled by the absolute derivative of the positive value of the pseudo-analog signal. The derivative is obtained by a circuit comprising an RC filter receiving the pseudo-analog signal and a memory controlling the value of the impedance of the filter. The invention has particular application to the restitution of graphic or iconographic documents which have been previously digitally encoded.

Abstract: ABSTRACT OF THE DISCLOSURE           A keyboard-controlled microprocessor-based tissue stimulator includes pulse output circuits which deliver output pulses at times commanded by, and having amplitudes commanded by, a microprocessor-controller.  A microprocessor operates in response to user command on keyboard switches.  Commands include a stop command which not only terminates output pulses but resets amplitudes to a safe value so that subsequent restarting will not result in production of uncomfortably high output signal levels.        The stop switch is prominently located on the tissue stimulator housing to permit the user to stop operation very quickly in an emergency situation.  Keyboard switches are provided for increas-ing and decreasing output amplitude, and the microprocessor-controller responds to those commands by continuously changing output amplitude by predetermined small increments for as long as the switch remains depressed, thus permitting the user to make smooth and precise adjustments for optimum results.  A further keyboard switch commands the microprocessor-controller to switch to an alternate mode, for example, a low rate burst mode.

Additional metallic reducing agent is added to the slag phase at an empirically determined rate during the heating thereof, until substantially complete trans-formation of all the metal oxide remaining in the slag phase and migration of the resulting metal into the metal phase.
